OBJECTIVE The aim was to determine the antimicrobial effect of ozonated water, ozonated water with ultrasonication, sodium hypochloride and chlorhexidine (CHX) in human primary root canals contaminated by Enterococcus faecalis (E. faecalis). MATERIALS AND METHODS Fifty-eight extracted human primary molar teeth were used. Crowns were cut off using a diamond saw under water-cooling. One hundred...

The aims of this study are to increase and explain the mechanism of dissolution enhancement of isradipine using the sonoprecipitation method for stable nanosuspensions. There have been still few of published researches on formulation of isradipine using nanoparticle engineering. Nanosuspension systems were prepared upon various factors including amplitude and the time length of ultrasonication....

• Ultrasonication-assisted synthesis of MoS 2 nanosheets improved PEC performance. Liquid phase exfoliation was used for with 6 nm thickness. Photocurrent ?-Fe O 3 photoanode significantly increased by heterojunction. /8-MoS showed a thinner space charge layer and reduced flat band potential. p-n junction decreased resistance due to the recombination rate carriers. This study successfully manuf...

Abstract This study aims to examine the effect of ultrasonic-assisted extraction method on yield oil and profile fatty acid from microalga yeast. The cultivated was identified genetically as Thraustochytrium multirudimentale MAST-1 yeast Rhodotorula mucilaginosa KAST-1. oils were extracted dried biomass by solvents using modified Bligh Dyer (BD) method. Before extraction, material underwent ult...
